    C Wrapper dll SetFrameReadyCallback Image flipped

    Hello again!

    I am using IC_SetFrameReadyCallback of the C Wrapper dll (tisgrabber.dll version 3.2.0.4) with QT environment.
    In the callback fonction, the image I get from the buffer is always flipped (vertically or horizontally), either showed by a QT windows or saved by Opencv.
    I tried with IC_SnapImage and IC_StartLive, the image is correct.
    It looks like that the image in the buffered is set to be flipped but I don't find how to get the flip property, or how to set it by the C Wrapper dll.
    My camera is DMK 72AUC02.

    Thanks in advance for any advice.

    Best regards,
    Shuji

    Re: C Wrapper dll SetFrameReadyCallback Image flipped

    Hi

    This is normal. If the image provided from IC Imaging Control is forwared to OpenCV, the image is bottom up.

    I suggest to flip the image with the appropriate OpenCV function.
    Best regards

    Thank you Stefan for your answer, I will flip it by OpenCV function.
